Ersatz von M e t a l l g a l v a n o s, S t e r e o t y p i e n, A t z u n g e n u n d d g l.
In dem Stammpatente Nr. 60173 wurde ein Verfahren beschrieben, nach welchem es möglich ist, plastische Massen, die in millimeterdicken oder stärkeren Platten aus azetonlöslicher Azety1zel1ulose hergestellt werden können, dadurch zu Klischees und ähnlichen Formen zu verarbeiten, dass man sie über ihren Schmelzpunkt erhitzt und gegen die abzuformenden Gegenstände bzw. gegen Matrizen, die aus dem gleichen oder einem anderen Material bestehen können, presst.
Es hat sich nun gezeigt, dass man sowohl als Matrizen wie als K1ischoemateria1 auch andere, aus Celluloseestern hergestellte Massen benutzen kann, als diejenigen, welche aus azetonlöslicher Azetylzellulose bestehen, vorausgesetzt, dass die aus andern Estern hergestellten Massen nur relativ geringe Mengen von Erweichungsmitteln (Kampferersatzmitteln bzw. hochsiedenden Lösungsmitteln) enthalten, so dass sie einen Zelluloidartigen oder hartgummiartigen Charakter besitzen und bei gewöhnlicher Temperatur vollkommen hart sind, bei Temperaturen von etwa j00 zu erweichen beginnen.
Als soche Massen kommen in Fragu Mtschungeu von Zellulosetriazetat mit
EMI1.1
oder in verdünntem Alkohol iöshch sind), ferner solche aus den Ameisensäure-, Buttersäure-und anderen Estern der Zellulose, sowie auch gemischten Estern derselben durch Verarbeitung mit hochsiedenden Lösungsmitteln erhalten werden.
So werden beispielsweise 10 kg chloroformlösliche Azetylzellulose mit 5 leg Azetylentetrachlorid und 3 kg Manol im Mischapparat solange verknetet, gegebenenfalls unter Steigerung der Temperatur auf 40 bis 50 , bis eine gleichmässig gequollene Masse entstanden ist. Diese wird dann zwischen Walzen ausgewalzt, bis das Lösungsmittel grösstenteils verdunstet ist und durch Pressung in Plattenform gebracht. Die getrockneten, vom Lösungs-
EMI1.2
schon beim Erkalten unter 700, also auf der noch warmen Platte, unveränderlich bestehen.
Es hat sich ferner als zweckmässig erwiesen, die Oberflächenhärte derjenigen Platten, welche als Matrize dienen sollen, von denjenigen der als Patrize zu verwendenden Platten verschieden zu gestalten. Dies kann dadurch geschehen, dass man die härteren Platten aus Celluloseestern mit geringerem Zusatz an Kampferersatzmitteln herstellt als die weicheren Klischeeplatten oder den plastischen Massen aus Zelluloseestern und Kampferersatzmitteln noch pulverförmigo Substanzen, wie Tonerde, Glimmer, amorphe Kieselsäure usw. hinzufügt.
Je nach der Art und der Menge dieser Füllstoffe werden die Platten in bezug auf ihre Härte, ihre Druckfestigkeit und ihren Schmelzpunkt verändert und kann beispielsweise eine Platte der obengenannten Zusammensetzung als Klischeematerial benutzt werden und ein analoges

Replacement of M e t a l l g a l v a n o s, S t e r e o t y p i e n, A t z u n g e n u n d d g l.
In the parent patent no. 60173, a process was described by which it is possible to process plastic masses, which can be produced in plates of acetone-soluble acetone-cellulose in millimeter-thick or thicker plates, into clichés and similar shapes by heating them above their melting point and processing them against the objects to be molded or against matrices, which can consist of the same or a different material.
It has now been shown that other masses made from cellulose esters can be used both as matrices and as K1ischoemateria1 than those made from acetone-soluble acetyl cellulose, provided that the masses made from other esters only contain relatively small amounts of emollients (camphor substitutes or high-boiling solvents), so that they have a celluloid-like or hard rubber-like character and are completely hard at ordinary temperature, but begin to soften at temperatures of around 100.
Such masses come along with cellulose triacetate in Fragu
EMI1.1
or are soluble in dilute alcohol), and those from the formic acid, butyric acid and other esters of cellulose, as well as mixed esters thereof, are obtained by processing with high-boiling solvents.
For example, 10 kg of chloroform-soluble acetyl cellulose with 5 legs of acetylene tetrachloride and 3 kg of manol are kneaded in a mixer, if necessary while increasing the temperature to 40 to 50, until a uniformly swollen mass is formed. This is then rolled out between rollers until the solvent has largely evaporated and pressed into a plate shape. The dried, from the solution
EMI1.2
already exist when cooling below 700, i.e. on the plate that is still warm.
It has also proven to be useful to design the surface hardness of those plates which are to serve as a die differently from that of the plates to be used as a male die. This can be done by making the harder plates from cellulose esters with less addition of camphor substitutes than the softer cliché plates or by adding powdered substances such as clay, mica, amorphous silica etc. to the plastic masses of cellulose esters and camphor substitutes.
Depending on the type and amount of these fillers, the plates are changed with regard to their hardness, their compressive strength and their melting point and, for example, a plate of the above-mentioned composition can be used as the cliché material and an analog one
